General Information- Inch/Metric conversions may not be direct conversions.SERIES XGENERAL INFORMATIONREFERENCE NOTES- Our standards apply unless otherwise specified.- All Dimensions are for reference only and are subject to change without notice unless certified.- Unless otherwise specified, our coupling hubs will be bored for CLEARANCE FIT with a setscrew OVER the keyway orINTERFERENCE FIT without a setscrew.- Torque ratings of couplings utilising Taper-Lock bushings can differ from those that do not. Refer to our Applica tionEngineers for details.- If we are to supply coupling hubs bored for Taper-Lock bushings, the bushing manufacturer MUST be noted on the order.- Consult our Application Engineers when limited end float is required. -Refer to our Application Engineers for bore limitationson hubs requiring Puller Bolt holes.Reference Notes† Peak torque capacity is two times the published rating. Consult our Application Engineers for higher speeds.• Maximum bores are reduced for hubs furnished with an INTERFERENCE FIT and a setscrew OVER the keyway.Recommended key sizes for the listed maximum bores are shown in each of the coupling type sec tions.∆ Minimum bore is the smallest bore to which a RSB hub (rough stock bore) hub can be bored. Depending upon couplingsize, rough stock bore hubs may have only a blind centering hole or a through hole that will permit re-machining of thehubs to the minimum bores specified.◊Sizes 5R - 50R Nylon cover furnished as standard and Epoxy coated steel cover available upon request. For Sizes 60R -80R Epoxy coated steel cover is standard (Nylon cover not available).Cover fasteners are ISO 7380 Socket Button Head Capscrews. Two cover fasteners per coupling.To obtain total weight: Basic Coupling + BE times kg per mm of BE.To obtain total WR 2 : Basic Coupling + BE times WR 2 per mm of BE.Values shown are based on no angular misalignment. The axial centering force restricts motor end float and satisfiesthe requirements of NEMA standards MG1 -14.37, 1-20.81 and 1-21.81.§ Interpolate for intermediate speeds. Maximum BE is based on 70% of critical speed. Refer to our Application Engineersfor higher running speeds.Long Term Grease (LTG)The high centrifugal forces encountered in couplings separate the base oil and thickener of general purpose greases. Heavythickener, which has no lubrication qualities, accumulates in the tooth mesh area of gear couplings resulting in prematuremesh failure unless periodic lubrication cycles are maintained. Long Term Grease (LTG) was developed specifically forcouplings. It resists separation of the oil and thickener and is an extreme pressure grease. Although LTG grease is compatiblewith most other coupling greases, the mixing of greases may dilute the ben efits of LTG.Benefits include: increased coupling life, significantly extended re-lubrication intervals, reduced maintenance costs, reduceddowntime, superior lubrication, high load carrying capabilities and it is usable up to 121 o C (250 o F).4

SERIES XSELECTION PROCEDUREStandard Selection MethodThe standard selection method can be used for mostmotor, turbine, or engine driven applications. The followinginformation is required to select a gear coupling.• Kilowatt (kW) or torque (Nm).• Running rpm.• Application or type of equipment to be connected(motor to pump, drive to conveyor, etc.).• Shaft diameters.• Shaft gaps.• Physical space limitations.• Special bore or finish information and type of fit.Exceptions are High Peak Loads and Brake Applications.For these conditions, use the Formula Selection Methodin the next column, or consult one of our ApplicationEngineers for assistance.1. RATING: Determine system torque. If torque is notgiven, calculate as shown below.System Torque (Nm) = kW x 9549rpmWhere: kW (Kilowatt) is the actual or transmittedpower required by the application (if unknown, usethe motor or turbine nameplate rating) and rpm is theactual speed the coupling is rotating. Applications thatrequire rapid changes in direction or torque reversalsshould be referred to our Application Engineers.1. SERVICE FACTOR: Determine the appropriateservice factor from Table 1, Page 6.2. REQUIRED MINIMUM COUPLING RATING:Determine the required minimum coupling ratingas shown below Minimum Coupling Rating = S.F.(Service Factor) x Torque (Nm)3. SIZE: Turn to appropriate pages for the coupling typechosen and trace down the torque column to a valuethat is equal or greater than that determined in Step 3above. The coupling size is shown in the first column.4. CHECK: Check speed (rpm), bore, gap anddimensions.Formula Selection MethodThe Standard Selection Method can be used for mostcoupling selections. The procedure below should be usedfor:• High Peak Loads• Brake Applications (where the disc brake orbrakewheel is to be an integral part of the coupling,consult our Application Engineers for design options).Providing system peak torque and frequency, duty cycle, andbrake torque rating will allow for a more refined selectionusing the Formula Selection Method.1. HIGH PEAK LOADS: Use one of the followingformulas for applications using motors with torquecharacteristics that are higher than normal;applications with intermittent operations, shockloading, inertia effects due to starting and stoppingand or system induced repetitive high peak torques.System Peak Torque is the maximum torque that canexist in the system.Select a coupling with a torque rating equal to orgreater than selection torque calculated below.A. NON-REVERSING HIGH PEAK TORQUESelection Torque (Nm) = System Peak TorqueorSelection Torque (Nm) = System Peak kW x 9549rpmB. REVERSING HIGH PEAK TORQUESelection Torque (Nm) = 1.5 x System Peak TorqueorSelection Torque (Nm) = 1.5 x Peak kW x 9549rpmC. OCCASIONAL PEAK TORQUES (Non-Reversing)If a system peak torque occurs less than 1000 timesduring the expected coupling life, use the followingformula:Selection Torque (Nm) = .5 x System Peak TorqueorSelection Torque (Nm) = .5 x Peak kW x 9549rpmFor reversing service, select per Step B, above.2. BRAKE APPLICATIONS: If the torque rating of thebrake exceeds the motor torque, use the brake ratingas follows:Selection Torque (Nm) = Brake Torque Rating x S.F.5

Type G52 Standard Flanged SleeveFloating Shafts / Dimensions - MillimetersA standard floating shaft assembly consists of two standard singleengagement couplings, two gap discs and a connecting shaft.A floating shaft can eliminate the need for additional bearingsupports along spanning shaft because the shaft is supported atthe ends by connected equipment through the single engagementcouplings.Flex Hubs on Floating Shaft (RFFR)Assembly of the flex hubs on the floating shaft allows for easierreplacement in case of wear and allows the rigid hubs with theirincreased bore capacity to be used on the connected equipmentshafts. This frequently means a smaller coupling size can beutilised.Operating speed - RPMBalancing normallynot requiredBalancing of shaftrequiredDistance between shaft ends - MillimetersSERIES XDIMENSIONS ANDSPECIFICATIONSRigid Hubs on Floating Shaft (FRRF)When the rigid hubs are on the floating shaft, shorter shaft spanscan be accommodated, since no cover drawback is required. Sincethe flex hubs are outboard, the points of articulation are furtherapart, providing greater offset misalignment capacity.Solid Floating Shaft SelectionSingle Engagement Type G52/GV52 couplings are used withfloating shafts in either horizontal or vertical applications. Forvertical applications select a Type GV52 coupling for the lowercoupling assembly. Select floating shafts as follows:1. Use the Standard or Formula Selection Methods, Page 5 toselect the couplings. Record the Required Minimum CouplingRating from standard selection method or Selection Torquefrom formula selection method.2. From table below select a shaft diameter that has an assemblytorque rating equal to or greater than the system or selectiontorque determined in coupling selection.3. Check maximum ‘BE’ for the shaft diameter selected andrunning speed for shaft length required from table below. Referto graph at left to determine if shaft requires balancing.4.

Type G52 Steel Mill Flanged SleeveFloating Shafts / Dimensions - MillimetersA standard floating shaft assembly consists of two standard singleengagement couplings, two gap discs and a connecting shaft.A floating shaft can eliminate the need for additional bearingsupports along spanning shaft because the shaft is supported atthe ends by connected equipment through the single engagementcouplings.Flex Hubs on Floating Shaft (RFFR)Assembly of the flex hubs on the floating shaft allows for easierreplacement in case of wear and allows the rigid hubs with theirincreased bore capacity to be used on the connected equipmentshafts. This frequently means a smaller coupling size can beutilised.Operating speed - RPMBalancing normallynot requiredBalancing of shaftrequiredDistance between shaft ends - MillimetersSERIES XDIMENSIONS ANDSPECIFICATIONSRigid Hubs on Floating Shaft (FRRF)When the rigid hubs are on the floating shaft, shorter shaft spanscan be accommodated, since no cover drawback is required. Sincethe flex hubs are outboard, the points of articulation are furtherapart, providing greater offset misalignment capacity.Solid Floating Shaft SelectionSingle Engagement Type GF52 couplings are used with floatingshafts in horizontal applications. Select floating shafts as follows:1. Use the Standard or Formula Selection Methods, Page 5to select the couplings. Record the Required MinimumCoupling Rating from standard selection method or SelectionTorque from formula selection method.2. From table below select a shaft diameter that has an assemblytorque rating equal to or greater than the system or selectiontorque determined in coupling selection.3. Check maximum ‘BE’ for the shaft diameter selected andrunning speed for shaft length required from table below. Referto graph at left to determine if shaft requires balancing.4. If the application shaft length exceeds the maximum “BE” listed,select the next larger shaft diameter or the next larger sizecoupling.

SERIES XGENERAL DESCRIPTIONGrid CouplingsThe Simplest, Most Cost- Effective Couplings For HighTorque Applications.With overall savings in initial costs, spare parts costs, andlabour costs for installation, alignment and replacement -plus improved ratings and a 5 Year Heavy-Duty Warranty- it’s easy to see what our Grid Couplings have over thecompetition. No other coupling in the torque range cantouch our Grid couplings for cost-effective performance andreliability.Features That Give Grid Couplings The Lowest LifetimeOperating CostLonger LifeTapered grids, made of high strength alloy steel, arequenched and tempered to spring hardness. The gridsurface is then precision shot peened to compress thesurface molecules.The effect is a dramatic increase in rating, providing reservestrength for longer life or allowing a smaller size coupling tobe selected. This precision technology was originally used inthe production of sophisticated aircraft components.Extended Maintenance PeriodsNow you can install our Grid couplings and lubricate it withour Long Term Grease (LTG) and forget periodic, routinemaintenance. Our LTG Grease was developed specificallyfor couplings. It resists the separation of the oil andthickening agent that occurs in typical greases. The initialuse of LTG Grease will eliminate routine lubrication cycles.Quick, Easy Installation ... Replace-In-Place DesignThe grid is the wearing member of our Grid coupling andit is a fraction of the complete coupling cost. Tapered gridsare accessible through the quickly removable cover. Thereplace-in-place design of the replacement grids allowsthem to be dropped in without the need to replace hubsor move and realign shafts and connected equipment asrequired with gear couplings and many elastomer designs.Equipment Protection Against Shaft Misalignment DesignThe grid is free to rock, pivot and float within the hubteeth. Generous misalignment capacity is provided withoutproducing detrimental bearing side loads created by othercoupling types.Light LoadHeavy LoadContact IncreasesLow ContactPivotsFloatsRocksEquipment Protection Against Shock / Vibratory LoadsTorsional flexibility is the ability of our Grid Couplings totorsionally deflect when subjected to normal shock orvibratory loads, providing flexible accommodation to changingload conditions. It absorbs impact energy by spreading it overan increment of time. It damps vibration and reduces peak orshock loads by a much as 30%. It is a true shock absorber forrotary motion.Versatile DesignsTwo cover designs are available in the popular sizes.Standard spacer, piloted, high speed, brake wheel or disc,and controlled torque designs are also available.Worldwide AvailabilityGrid couplings and component parts, in popular sizes andtypes, are available from our worldwide distribution networkwith the largest stock of any shaft coupling on the market. Ourgrid couplings are warranted for 5 Years when lubricated withour LTG Long Term Grease.33

Type T50Floating Shaft/SelectionIntroduction - Floating shaft diameters have been pre-selectedto transmit the coupling torque and need only to be checked forallowable speed.Construction - Standard shafts are solid, AISI 1018 or 1020 coldrolled steel. Also available is an optional solid, AISI 1018, fullyturned, hot rolled steel shaft.Determine the Allowable Shaft LengthA. Select the coupling size per Pages 5 and 39.B. From Page 39, determine shaft diameter (Dimension SD) forthe coupling selected.C. From table below locate the floating shaft diameter (DimensionSD) determined in Step B.D. Determine the allowable shaft length for the required operatingspeed.SERIES XDIMENSIONS ANDSPECIFICATIONSFor Speeds under 540 rpm - Read the maximum allowableshaft length to the left of the required shaft diameter.For Speeds over 540 rpm - Trace right from the shaftdiameter determined along the diagonal line to the point ofintersection with the required vertical operating speed line. Traceright along the horizontal line to the right and read the maximumallowable shaft length.E. Determine if shaft requires balancing. Locate point whereoperating speed and floating shaft length cross. Balance isrequired when point is located to the right of bold line.F. If a longer shaft is required, reduce the operating speed ifpractical, or select the next larger size coupling.NOTE: For such conditions, the use of a tubular shaft designshould be considered, refer to our Application EngineersTable 17 - Floating Shaft SelectionsMax.

SERIES XGENERAL DESCRIPTIONCone Ring CouplingsPin and bush elastomer Couplings611 Heavy Duty Straight Bored613 Heavy Duty Taper Bushed612 Medium Duty Straight Bored614 Medium Duty Taper BushedGeneral DescriptionFlexible Cone Ring couplings, types 61,612,613, 614 areavailable with bore sizes up to 355 mm diameter and a basicrated torque up to 188700 Nm.Operational DetailsThey accommodate all types of shaft misalignment met innormal operation, being a development of the old pin andbush design which it resembles in simplicity and ease ofassembly and dismantling. It differs fundamentally in theway in which the resilient material behaves by substitutingthe parallel bush with a series of rubber rings of conicalsection. This provides greatly improved torsional flexibilitytogether with a limited freedom of axial movement of oneconnected shaft relative to the other.Types AvailableTwo options are available, MEDIUM DUTY and HEAVYDUTY.Medium duty couplings (types 612 and 614) are identical toheavy duty couplings (types 611 and 613) except that theyare supplied with only half the standard number of pin andring assemblies. This enables a useful cost saving to bemade when the size of coupling is determined by the shaftdiameter rather than the coupling’s torque capacity.Taper BushingFlexible Cone Ring couplings are also available with taperbushes (types 613 and 614) with bore sizes up to 125mm(4.92 inch) diameter, providing ease of assembly anddismantling together with flexibility to change shaft sizes bychanging only the taper bushes.46
